Beschreibung
Zusammenfassung:	The present invention provides an electric generating system using a solar cell to improve the quality of output power by including a converter for converting an output voltage generated from the solar cell into a DC voltage in a pulse shape, an inverter for converting the DC voltage in the pulse shape into an AC voltage and applying the AC voltage to a power system and a control device for determining whether an erroneous operation of the electric generating system using the solar cell is generated or not based on an output voltage of the solar cell, an output current of the solar cell and a voltage of the power system and for controlling in such a way that at least one inverter switching device among a plurality of inverter switching devices performs a switching at a frequency higher than a frequency during a normal operation at an interval where the erroneous operation is generated.
